GUARD FOR DGOR-LATCHES.

newest.

To all whom it may concern:

lie it known that'l, (Irmnnns F. KLINE, citizen of the United States, residing at Cleveland, in the county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in. Guards for Door-Latches, of which the following is a speci fication.

the invention herein. has for its object to safeguard doors having spring'pressed looks or latches with beveled engaging ends and adapted to slide back and iorthinte and out of closing position in the usual latch plates. Generally such doors close against a removable janib or strip, and generally also the door fits loosely in its casing, so that, it one desires to pick the latch .he can release or remove the jemo and insert a thin knife blade or other thin strip of metal and by hearing against the exposed bevel of the latchQt'orce it back and open the door. This, in fact, is known especially well by l1ouse breakers and'burglars, andnlrequently is resorted to by this class of men to enter a dwelling or other edifice; Hence, I have conceived the idea of latch guard having the construction and adaptabilitysubstantially as shown and described and particularly pointed out in the claims.

in the accompanying drawings, Figure l is a perspective view of a section of a door casing and jamb and a latch plate thereon, and my safety guard in working; relations as to said plate and lamb. Fig. 2 is a cross section ot'said parts and of a section of the door witlr'the latch in engaging relations. FigJ-B a perspective view of the guard in its most simple form and as made in one piece, and Fig. is a perspective view of a modification oi the guard and as made in two pieces slid-ably and adjustably related.

As thus shown 0 represents the door casing and (Z the door. The said casing has the usual amb or strip 2 fixed on the casing and serving asa stop for the door. The

ing latch t supported on thedoor in the usual Wu y and having a usual beveled err-- tremity which comes outside in the latch plate and where the said bevel is exposed more or less when the jamh 2 is removed.

Now, as to the latch plate 3v and latch s ecimen of Letters Patent.

in any case being of such also,

engaged by the slid Serial No. 118,999.

house to house work and Installing my guard therein without any change or even plate, the'said guard length as to eX- cend past said plate at both ends more or less as may be preferred.

Thus, in Fig. 3, I. show a. guard plate 9 made in a single piece of comparatively thin but strong sheet metal, say sheet steel, which can be struck up to shape and has a role tively narrow body 5, an arm a at each end projecting inward and provided with a lonremoval of the latch gitudinal slot 6 through whichit is secured and right anby screws to the door casing, v

edge. In Fig.

gled flange 7 along its outer 1 it will be seen that both ends and arms of the guard are clear of the latch plate, and that the said guard is extended for enough past said plate above and below the some to prevent possible introduction or' a thin instrument of any kind to bear against the latch and force it back. l or this reason, 1 have made a modification of the said guard extensible lengthwise by constituting the same in two equal parts or pieces 8 having longitudinal slots in their overlapping portions and rivets 9 through said slots. This makes a guard adapted to be lengthened and also to b shorten-ed within limits, and ailords'a range of. adjustment and aplicability not present in' the guard, Fig. 3. In practice, the door casing and the jamb may be slightly recessed ,to place the guard flush with the respccti'ic surfaces.

Patented Feb. 13, lore,

one piece guard to doors of different thicknesses,"

which very important in a device of this kind. What I claim" is: v

1. As a new article, of manufacture, a guard for door latches consisting of sheet metal and having a relatively narrow body provided with a right angled flange along its'outer edge and a flat inward projection at each end in the plane of said body having 2. As a new article of manufacture, a guard for door latches constructed, of two '5 substantially equal members having over-" lapping sl'ottedends slidably connected, and each 'member having an inward projection at its outer end provided with a slot lengthwise thereof and a flange in overlapped re-,

lations with a flange on the other member. Signed at Cleveland, in the county of Cuyahoga, and State of Ohio, this 26th day.
